IPC: H04N9/86
Filed: 1993-12-29
Abstract: PURPOSE:To prevent invasion of noise with a muting circuit keeping an FM color signal stepped down to 1/4 for a non-signal period to a prescribed level. CONSTITUTION:A mute changeover switch 14f operated by an output Sgamma of a FF 14e at a rising of outputs of counters 14c, 14d is thrown to the position of a contact l by a 0 level of the output Sgamma and an output signal from a synchronization gate circuit 10 is fed to an equalizer circuit 12 via the contact l. For the non-signal period of the FM color signal when the signal Sgamma is set to logical 1, the witch 14f is thrown to the position of a contact (h) and the output signal of the circuit 10 is muted and a prescribed level signal obtained by dividing a DC voltage at a terminal 14g by resistors 14h, 14i is fed to the circuit 12. Since a noise is eliminated for a no-signal period where no color signal is substantially in existence from an output signal of the counter 9 by the circuit 10 and the mute circuit 14, the noise amplified by a limiter amplifier 8 is not invaded in the luminance signal when the FM color signal is recorded after 1/4 step-down by the circuit 12 to improve the quality of the reproduced picture considerably.

Title: Digital filter
Inventor: CHIBA KATSUHIKO
IPC: H03H17/04
Filed: 1995-12-28
Abstract: PROBLEM TO BE SOLVED: To provide a filter with cut-off frequency being an ultra-low frequency with high precision without increasing the scale of the hardware by providing an endless impulse response with a means conducting a prescribed arithmetic operation. SOLUTION: The output of an adder 3 delayed by a time T at a unit delay device 121 is shifted by one bit not via multiplication processing, that is, with a bit width of adder subtractor processing. Furthermore, the output is doubled by this bit shift and the high-order bits are fed back to an adder 3. Furthermore, a signal multiplied by a multiple of c1 at a multiplier 211 is fed back to the adder 3. The adder 3 adds digital signals with a wide bit width obtained by shifting outputs of multipliers 211, 212, 220, 221, 222 and the unit delay device and provides the output of the sum as an output signal. Since data of low-order bits of one period delay signal rounded for multiplication processing are reflected on the sum of the wide bit width from the adder 3, the filter with high precision is obtained even when the frequency is ultralow.
